Application led January 22, 1917. Serial No.A 143,807.

To all whom it may concern.'

Be it known that 1, RoER'r H. STEVENS, a citizen of the United States, residin at Newark,in the county of Essex and tate of New Jersey, have invented a new and useful Sanitary Closure for Containers, of which the following is a speciiication.

This invention relates to closures for containers, orreceptacles and is especially designed with reference to sanitary closures for milk bottles. The invention is equally applicable to any form of container such as boXes or packages for liquids and material in powdered form.

The object of the invention is to provide a closure that will be perfectly sanitary and will prevent the milk from running down the side of the bottle.

A further object is to provide a closure that will eliminate the necessity of removal of the ordinary closure, or milk cap, while pouring the contents of the bottle and while the bottle is being used for storage purposes.

In the accompanying drawings forming a part of this specification,

Figure l is a top plan view of the applicants closure.

Fig. 2 is a section taken on line X-X of Fig. 1.

Fig. 3 is a section similar to Fig 2 showingthe lid in raised position.

ig. 4 is a fragmental sectional view of the pouring spout showing the angular relation of the inner and outer beads.

The embodiment of applicants invention illustrated in the attached drawings discloses two thicknesses of material used in constructing the body portions comprising the upper and lower sections 4 and 5. The lower section is provided with the pouring orifice 7, ledge 8 and lip 10. The upper section is formed with a lid 12 having a projection, lip and lift when desired. Adjacent the rear of the orifice 7 the upper section is adapted to be bent back forming a hinge joint' 13. At the rear of the hinge joint'the upper and lower sections are secured together in any suitable manner as by pasting.

When pressed into the annular groove 2 of the bottle the lower lip 1() forms a pouring ledge which electually keeps the milk from flowing down the inside of the bottle. The upper lip perfectly covers the lower lip when in closed position thereby preventing any dirt or dust from coming in contact with the pouring channel of the milk.

The pouring spout 10 is formed inte ral with the lower or closure. member. his spout is angularly placed with respect to base member 5 and has its circumferential edge bent over to an acute angle of greater degree than that on the corresponding edge of the closure fiap thereby producing between the two members 10 and 12 sufficient friction and elasticity when in closed position to function as a lock. The lip or flap member is provided with a bead or depression 9 to lit tightly inside the pouring aperture 7 in lower member to centrally place and aid in holding the closure flap in sealing position.

Centrally located on the overturned edge of the closure flap is provided a lifting tab -11 to be gripped by the fingers in operating the closure.

T his invention is an improvement on the invention set forth in my prior pending application, Serial Number 113,390, filed 4August 5, 1916.

What I claim is In a closure the combination of a lower member having a pouring orice located within the circumferential limits of the member, an integral, angularly disposed circumferential pouring spout having an upper beaded edge, with an upper member having a depressed portion to snugly engage the opening in lower member and a portion of said upper member being formed into a closure iiap to completely cover the pouring spout when in closed position, and provided with a circumferential bead to coact with bead on the pouring spout to form a fastener for the closure flap.
